MOTOR-PLOW.

Specification of Letters Patent. Patented 0013.13, 1914;,

Application filed October 3, 1913. Serial No. 793,223. i

To all whom it may concern Be it known that 1, WILLIAM MEIDnN- BAUER, a citizen of the United States, reslding at Waukesha, in the county of Waukesha and State of Wisconsin, have 1nvented new and useful Improvements in Motor-Flows, of which the following is a specification.

This invention relates to motor plows, and it has for its object to provide in connection with a motor propelled Wheeled frame In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitatlon is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be. resorted to when desired,

In the drawings,-Figure 1 is a top plan view of the improved motor plow; Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation of a portion of the plow carrying frame showing the plow beam in raised position. Fig. 4: is a similar view of the same parts showing the plow beam in a lowered position. Fig. 5 is a perspective detail view of a portion of the main frame and a portion of the plow carrying frame to illustrate the guide means for the plow carrying frame. .Fig. 6 is a detail side elevation of the foot lever and related parts as viewed from the side opposite to that seen in Fig. 3.

Corresponding parts in the several figures are denoted by like characters of reference.

The main frame 10 which has been shown as being of rectangular shape is supported on front and rear aXlesll, 12 having ground wheels 18, 1 1. The rear axle 12 is supported for rotation and is driven by means of a chain 15 or in some other convenientmanner from a counter shaft 16, the latter being provided with opposed bevel gears 17, the hubs of which are provided with clutch members18, and either one of which may be engagedby an intermediate slidable double clutch member 19 operable by a shifting lever 20 soas to enable either one of the opposed bevel gears to be looked upon the shaft for rotation therewith. Both bevel gears 17 mesh with a pinion 21 on a driven shaft 22 which receives motion through intermediate gearing 23 from a motor 24, such as an internal combustion engine of any suitable and well known construction. A clutch 25 operable by a hand lever 26 is installed on the shaft 22 for the purpose of throwing the machine in and out of gear. The opposed bevel gears 17 and the clutch device cooperating therewith constitutes a reversing gear of simple and well known construction, whereby the direction of movement of the machine may be changed when desired. 1 p

a B designates a plow carrying frame which is composed of two longitudinal side bars 27 disposed in parallel relation and connected together at their front and rear ends by end members 28, whereby said side bars are spaced a short distance apart. The frame B is positioned below themain frame adjacent to one side-thereof, and it is provided with keepers 29 engaged by guide bars 30 that extend downwardly from one side member of the frame 10. The front and rear ends of the frame B are connected by links 31 with crank arms 32 extending laterally from the liftingv levers 331 which are fulcrumed on the main frame near the front and rear ends thereof, each of said lifting levers 33. being equipped with a stop member 3% adapted to engage a rack segment 35 for the purpose of maintaining the front and rear ends of the frame B in adjusted position.

36 designatesa plow beam carrying at its rear end a plow 37. The front end of the plow beam extends upwardly between the side bars 27 of the frame B and is provided with a cross bar 38 operating in slots 39 formed in the respective bars 27 Aspring 40 is provided which connects the plow beam with the frame B, the tension of said spring I, being exerted to move the plow beam upwardly so as to lift the plow from the ground and also forwardly so as to move the cross bar 38 forwardly with respect to the slots 39 wherein it is guided. The rear portion of the plow beam is connected with the frame B by means of a crank 41 which serves as a brace and also to guide the plow in its up and down movement.

For the purpose of raisin and lowering the plow withrespect to the frame B a hand lever 42 and a foot lever 43 are provided, said levers being fulcrumed on the plow carrying frame B. The hand lever 42 has a downwardly extending arm 46 which is pivotally connected with a link 47 that extends upwardly from the plow carrying beam 36. The arm 46 has a rearwardly extending bracket 48 provided with a laterally extending lug 49 lying in the .path of a set screw 50 which is threaded through the link 47 and which constitutes a stop to prevent movement in one direction beyond a predetermined point of the lever 42 and the link 47, respectively. The lug 49 and the set screw 50 combine to constitute a stop to prevent further movement after the pivotal connecting point 52 of the lever arm 46 and the link 47 passes a dead center, when the lever 42 is utilized for lowering the plow into the ground against the tension of the spring 40, thereby locking the plow in ground engaging position. The foot lever 43 has upwardly extending divergent arms a, b and a downwardly extending arm 53, the latter being pivotally connected with the upper end of a link 54, the lower end of which is connected with the plow beam. The upper end of the link 54 has a segmental ratchet head 55. Theupwardly extending arm ahas. a foot piece or treadle 44; the upwardly extending arm I) has a treadle or pedal 45 with which a suitably guided dog or pawl 56 is pivotally connected, said dog being actuated by a spring 57 whereby it will be normally held in engagement with the ratchet wheel 55 of the link 54.

It will be seen that the operator by placing his foot on the pedal 45 may rock the latter so as to disengage the dog 56 from the ratchet head 55, thereby releasing the plow beam and permitting it to be lowered, the lowering being controlled by the hand lever 42. When the plow is to be raised, the operator places his foot on the treadle 44, thereby assisting the lifting of the beam which is likewise controlled by the hand lever 42. When the plow beam is raised, the spring actuated dog 56 will slide over the ratchets of the head 55. It will thus be seen that the foot lever not only constitutes an auxiliary to the hand lever, but that the dog and ratchet head associated with said foot lever will serve to support the plow at the desired elevation.

Having thus described the invention, what is claimed as new, is

1. In a device of the class described, a main frame, a vertically adjustable plow carrying frame having side members provided with longitudinal slots, a plow beam having a cross bar guided in said slots, a spring connecting the plow beam with the frame and operating to move the plow beam in an upward and forward direction, and means for lowering the plow beam against the tension of the spring and for locking said beam in lowered position.

2. In a device of the class described, a plow carrying frame including side members having longitudinal slots, a plow beam having a cross bar guided in said slots, a lifting spring connecting the plow beam with the frame and operating to force said beam in a forward direction, a crank connecting the plow beam with the frame, and plow adjusting means including a hand lever and a foot lever, each fulcrumed on the frame and each having a downwardly extending arm, and links connecting said arms with the plow beam; one of said links being provided with an extension having a set screw cooperating with a stop member on the lever arm to form a locking device whereby the plow beam may be secured with the plow in ground engaging position.

3. In a device of the class described, a main frame, a vertically adjustable plow carrying frame having side members provided with longitudinal slots, a plow beam having a cross bar guided in said slots, a spring connecting the plow beam with the frame and operating to move the plow beam in an upward and forward direction, means for lowering the plow beam against the tension of the spring and for locking said beam in a lowered position, and means for raising the plow beam with the tension of the spring and for locking said beam in a raised position.

4.
